The relation of tc to ta temperature depends also on the luminaire design. If the measured tc temperature is approx. 5 K below tc max., ta temperature should be checked and eventually critical components (e.g. ELCAP) measured. Detailed information on request. 3.

Strip mm of insulation from the cables to ensure perfect operation of the push-wire terminals. Use one wire for each terminal connector only. Use each strain relief channel for one cable only. LED module/led Driver/supply wire preparation: mm² mm 3.3 Loose wiring Press down the push button and remove the cable from front.

The LED wiring should be kept as short as possible to ensure good EMC. The max. secondary cable length is 2 m (4 m circuit), this applies for LED output as well as for I-select 2. Secondary switching is not permitted. 4

5 The LED Driver has no inverse-polarity protection on the secondary side. Wrong polarity can damage LED modules with no inverse-polarity protection. Wrong wiring of the LED Driver can lead to malfunction or irreparable damage. To avoid the damage of the Driver, the wiring must be protected against short circuits to earth (sharp edged metal parts, metal cable clips, louver, etc.). 3.5 Hot plug-in Make sure that the LED Driver is operated within the given window under all operating conditions. Special attention needs to be paid at dimming and DC emergency operation as the forward voltage of the connected LED modules varies with the dimming level, due to the implemented amplitude dimming technology. Coming below the specified minimum output voltage of the LED Driver may cause the device to shut-down. See chapter 6.11 Light level in DC operation for more information. 4.2 Efficiency vs load Hot plug-in is not supported due to residual output voltage of > 0 V. If a LED load is connected the device has to be restarted before the output will be activated again. This can be done via mains reset or via interface (DALI, DSI, switchdim, ready2mains). 3.6 Earth connection The earth connection is conducted as protection earth (PE). The LED Driver can be earthed via earth terminal. If the LED Driver will be earthed, protection earth (PE) has to be used. There is no earth connection required for the functionality of the LED Driver. Earth connection is recommended to improve following behaviour: Electromagnetic interferences (EMI) LED glowing at standby Transmission of mains transients to the LED output In general it is recommended to earth the LED Driver if the LED module is mounted on earthed luminaire parts respectively heat sinks and thereby representing a high capacity against earth. 3.7 I-select 2 resistors connected via cable For details see: Installation note Max. torque at the clamping screw: 0.5 Nm / M4 4.

Dimming is realized by amplitude dimming. 5.2 Control input ready2mains (L, N) The digital ready2mains protocol is modulated onto the mains signal which is wired to the mains terminal (L and N). 5.3 switchdim Integrated switchdim function allows a direct connection of a pushbutton for dimming and switching. Brief push (< 0.6 s) switches LED Driver ON and OFF. The dimm level is saved at power-down and restored at power-up. When the pushbutton is held, LED modules are dimmed. After repush the LED modules are dimmed in the opposite direction. In installations with LED Drivers with different dimming levels or opposite dimming directions (e.g. after a system extension), all LED Drivers can be synchronized to 50 % dimming level by a 10 s push. Use of pushbutton with indicator lamp is not permitted. 4.8 Dimming characteristics Digital dimming value DALI 175 DSI Relative lighting level % Dimming characteristics as seen by the human eye 5. Interfaces / communication 5.1 Control input (DA/N, DA/L) Digital DALI signal or switchdim can be wired on the same terminals (DA/N and DA/L). The control input is non-polar for digital control signals (DALI, DSI). The control signal is not SELV. Control cable has to be installed in accordance to the requirements of low voltage installations. Different functions depending on each module. 6. Functions 6.1 Function: adjustable current The output current of the LED Driver can be adjusted in a certain range. For adjustment there are three options available. Option 1: DALI Adjustment is done by masterconfigurator (see masterconfigurator documentation). Option 2: I-select 2 By inserting a suitable resistor into the I-select 2 interface, the current value can be adjusted. The relationship between output current and resistor value can be found in the chapter Accessories I-SELECT 2 Plugs. Please note that the resistor values for I-select 2 are not compatible with I-select (generation 1). Installation of an incorrect resistor may cause irreparable damage to the LED module(s). Resistors for the main output current values can be ordered from Tridonic (see accessories). Option 3: ready2mains Adjustment is done by the ready2mains programmer and the corresponding configuration software (see ready2mains documentation). The priority for current adjustment methods is DALI (highest priority), I-select 2, ready2mains (lowest priority). 6

7 6.2 ready2mains configuration The ready2mains interface can be used to configure the main parameters of LED Drivers via the mains wiring, such as LED output current, CLO and DC level. These parameters can be adjusted either via ready2mains-capable configuration software or directly via the ready2mains programmer (output current only). 6.3 ready2mains dimming ready2mains allows for mains-based group dimming, controlled via the ready2mains protocol and appropriate dimming interfaces. For details on the operation of ready2mains and its components see the relevant technical information. 6.4 Short-circuit behaviour In case of a short-circuit at the LED output the LED output is switched off. After restart of the LED Driver the output will be activated again. The restart can either be done via mains reset or via interface (DALI, DSI, switchdim, ready2mains). 6.5 No-load operation The LED Driver will not be damaged in no-load operation. The output will be deactivated and is therefore free of voltage. If a LED load is connected the device has to be restarted before the output will be activated again. 6.6 Overload protection If the output voltage range is exceeded the LED Driver turns off the LED output. After restart of the LED Driver the output will be activated again. The restart can either be done via mains reset or via interface (DALI, DSI, switchdim, ready2mains). 6.7 Overtemperature protection The LED Driver is protected against temporary thermal overheating. If the temperature limit is exceeded the output current of the LED module(s) is reduced. The temperature protection is activated approx. +5 C above tc max (see page 2). On DC operation this function is deactivated to fulfill emergency requirements. 6.8 corridorfunction The corridorfunction can be programmed in two different ways. To program the corridorfunction by means of software a DALI-USB interface is needed in combination with a DALI PS. The software can be the masterconfigurator. To activate the corridorfunction without using software a voltage of 230 V has to be applied for five minutes at the switchdim connection. The unit will then switch automatically to the corridorfunction. Note: If the corridorfunction is wrongly activated in a switchdim system (for example a switch is used instead of pushbutton), there is the option of installing a pushbutton and deactivating the corridorfunction mode by five short pushes of the button within three seconds. 6.9 Constant light output (CLO) The luminous flux of a LED decreases constantly over the life-time. The CLO function ensures that the emitted luminous flux remains stable. For that purpose the LED current will increase continuously over the LED life-time. In masterconfigurator it is possible to select a start value (in percent) and an expected life-time. The LED Driver adjusts the current afterwards automatically Power-up/-down fading The power-up/-down function offers the opportunity to modify the on-/off behavior. The time for fading on or off can be adjusted in a range of 0.2 to 16 seconds. According to this value, the device dims either from 0 % up to the power-on level or from the current set dim level down to 0 %. This feature applies while operating via switchdim, ready2mains and when switching the mains voltage on or off. By factory default no fading time is set (= 0 seconds) Light level in DC operation The LED Driver is designed to operate on DC voltage and pulsed DC voltage. For a reliable operation, make sure that also in DC emergency operation the LED Driver is run within the specified conditions as stated in chapter 4.1 operating window. Light output level in DC operation: programmable % (EOFi = 0.13). Programming by DALI or ready2mains. In DC operation dimming mode can be activated. The voltage-dependent input current of Driver incl. LED module is depending on the used load. The voltage-dependent no-load current of Driver (without or defect LED module) is for: AC: < 17.2 ma DC: < 1.9 ma 6.12 Software / programming With appropriate software and an interface different functions can be activated and various parameters can be configured in the LED Driver. To do so, a DALI-USB or ready2mains programmer and the software (masterconfigurator) are required masterconfigurator From version 2.8: For programming functions (CLO, I-select 2, power-up fading, corridorfunction) and device settings (fade time, epoweronlevel, DC level, etc.). For further information see masterconfigurator manual deviceconfigurator PC (windows) based software application to transfer parameters into our drivers. Workflow optimised for the use in OEM production line. For further information see deviceconfigurator manual. switchdim and corridorfunction are very simple tools for controlling gears with conventional pushbuttons or motion sensors. To ensure correct operation a sinusoidal mains voltage with a frequency of 50 Hz or 60 Hz is required at the control input. Special attention must be paid to achieving clear zero crossings. Serious mains faults may impair the operation of switchdim and corridorfunction. 7

8 7. Miscellaneous 7.1 Isolation and electric strength testing of luminaires Electronic devices can be damaged by high voltage. This has to be considered during the routine testing of the luminaires in production. According to IEC Annex Q (informative only!) or ENEC 303-Annex A, each luminaire should be submitted to an isolation test with 500 V DC for 1 second. This test voltage should be connected between the interconnected phase and neutral terminals and the earth terminal. The isolation resistance must be at least 2 MΩ. As an alternative, IEC Annex Q describes a test of the electrical strength with 1500 V AC (or x 1500 V DC). To avoid damage to the electronic devices this test must not be conducted. 7.2 Conditions of use and storage Humidity: 5 % up to max. 85 %, not condensed (max. 56 days/year at 85 %) Storage temperature: -40 C up to max. +80 C The devices have to be acclimatised to the specified temperature range (ta) before they can be operated. 7.3 Additional information Additional technical information at Technical Data Guarantee conditions at Services Life-time declarations are informative and represent no warranty claim. No warranty if device was opened. 8
